Hey Builders!
I have designed some PCBs for tube amplifiers. And have ordered some of each design.
I will be selling these here, for 7.50USD each. Will provide nearly unlimited support over telegram if you purchase some.
Shipping at current PostNL rates. Which are about 12 USD for a 400Gr parcel to North America, and lower for Europe.
I can also supply parts kits for the electronics, and help you source parts.
Cheers, V4lve Lover.

This is the universal Power supply board for tube amplifiers, can be used with snap-in capacitors up to 500V working voltage. But for the EL84PP and SE amps one does not need to go that high B+ Wise.
Can be used with CLCRC or CRCR filtering. Solid state rectification using UF5408 diodes.
It measures 50x150mm with M4 mounting holes on a 5mm grid.
Price 7.50USD each, 10 available.
I will help you design a PSU if you need, and provide pointers how to use PSUD2 for example.

These are 100x100mm Boards for building a EL84 push-Pull amplifier with ECC82/12AU7 phase splitter. The phase splitter is taken straight out of the ECC82 data-sheet by Philips.
The boards are very useful in that they have 3mm holes in the centre of each tubes, so the PCB's can be used to drill a chassis before soldering them.
Can be used in triode, pentode or UL.
Beware that this setup does not have enough gain from a low-output source. So you may need to use a pre-amplifier.
Price: 7.50 USD each, you need two for a stereo setup.
About a dozen working amplifiers have been made with these boards that i know of. Attached is a chassis picture of a recent amplifier using Toroidy iron.

These are Boards for a EL84SE amplifier that is very simple to construct. It is mechanically the same as the EL84PP boards.
Driver can either be an ECC82/12au7 or ECC83 12ax7. Or even 6NX Russian/Chinese tubes if you wire the heaters up differently from a 12AX7 variant.
Asking 7.5USD each. Will help with sourcing parts if needed.

Yes I can provide a BOM if needed, but some resistor values depend on the output configuration used. E.G. UL Triode or pentode.
I have some 12AX7s and 12AU7s so the triode list is what I need. I will give this a go. How can we arrange it?
